Sunlight to Energy: The Dance of Photosynthesis and Cellular Respiration

Explore the vital processes of photosynthesis and cellular respiration in plants, understanding how sunlight is converted into sugar and sugar into energy. Discover the key players, chloroplasts, and mitochondria, and learn how these organelles function differently. Uncover the shared elements between the two processes - glucose, oxygen, carbon dioxide, and water - and witness the cyclic relationship between them. Delve into the concept that one organelle's waste is another's fuel, and how cellular respiration can still occur in low oxygen environments through fermentation. Join the journey from sun to energy, and delve into the fascinating world of plant biology!

  1. PHOTOSYNTHESIS….Using sunlight to make sugar…….AND CELLULAR RESPIRATIONUsing sugar to make energy Moo.

  2. The Players ..and what’s in them. IN PLANTS ONLY Chloroplasts - Organelles found only in plant cells that carry out photosynthesis. Mitochondria - Organelles found in plant and animal cells that carry out cellular respiration. (Cows have no chlorplasts. If they did, they’d be green.) IN BOTH

  3. Photosynthesis Glucose C6H12O6 Carbon Dioxide CO2 Sun Energy Chloroplast Water H2O Oxygen O2

  4. Cell Respiration CO2 Carbon Dioxide C6H12O6 Glucose Energy (Stored in ATP) Oxygen O2 H2O Water

  5. RESPIRATION CARBON DIOXIDE OXYGEN ENERGY GLUCOSE WATER ATP C6H12O6 + 6O2 produces 6CO2 + 6H2O + PHOTOSYNTHESIS SUN + ENERGY CARBON DIOXIDE GLUCOSE OXYGEN WATER produces 6O2 C6H12O6 + 6CO2 + 6H2O +

  6. MORAL OF THE STORY:One organelle’s trash is another organelle’s treasure.

  7. But what if there isn’t much oxygen available? Can cellular respiration still occur?

  8. Yes.Fermentation (Anaerobic Respiration) Animal Cells Yeast Cells Products Products Less ATP Ethanol Less ATP Lactic Acid BEER! CRAMPS!
